I have a Java-Server with an open websocket connection to the javascript client. I want to transfer a binary file from the java server to the javascript client so that the user just has to save the file somewhere in the filesystem.

On client side I could easily handle a Blob. On server side I have a java.io.File and a javax.websocket.Session. I could simply write to the javax.websocket.Session.getBasicRemote().getSendStream().

Does anyone have such an example or can tell me if I am right and what I have to do on client side?

@grsdev7 IMHO: websocket != socket & java != javascript – eventhorizon Nov 24 '16 at 10:40
